What happens from time to time:
The user might already have registered before or maybe he / she already has an account created by the organizers (e.g. as Reviewer, PC Member or Chair).
Please go to:
Overview => User and Participant Management => List of All UsersUse the search function here to find out whether the
user does already have an account.
